Idiopidae, also known as armored trapdoor spiders, is a family of mygalomorph spiders first described by Eugène Simon in 1889. They have a large body similar to tarantulas. Description In some species the males have a spur on their legs, which they will show if provoked. Idiopidae build burrows, and some species close these with a door. The about 2 cm long Prothemenops siamensis from Thailand builds its retreat in a streamside vertical earth bank in lower montane rain forest. Each burrow had two or three entrances that lead into a main tube. Its lateral posterior spinnerets are elongated. The oldest known idiopid, Number 16, died at the age of 43 years.
